To all whom it may concern:

Be it known that we, Eonnnr H. Gone and lflowano A. RUssnLL. citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain. new and useful Improvements in Hose Couplings, of which the following is a specification.

Our invention relates to a hose coupling for connecting the rubber hose, or equivalent flexible conduit members on the train pipes of the adjacent cars of a railway train or for use in connecting pipe or hoses in other similar situations; the invention being concerned particularly with the type of conplin in which one or each of the mating couplers comprises a conduit member, prefcrably provided with a gasket to bear against a correspoiulingr part of the mating coupler, a coupling member through which the conduit member extends adapted to interlock with the uniting, coupler, and means for t- 'l ecting a relative movement between said conduit and coupling members which makes eli'ectual the interlock of one coupler with the other and forces the conduit member into (lose contact with the conduit member of the other coupler. I

The principal object of the invention is to provide a new and improved coupler of the type indicated which will be simple in its construction, economical to manufacture, of compact structure, and light in weight while providing eiiective means for insuring a reliable interlock between the coupler and its mate.

This application is a division of my co- )ending application Serial No. 557,675, filed May 1, 1922, which has matured into Patent No. 1,510,000 dated Sept. 30, 1924.

In describing the invention it will be assumed that both members of the coupling, that is, both couplers, are of the same construction. It will be obvious, however, that not essential so long as such coupler is so constructed as to mate with the other. The

invention is illustrated in the accompanying drawing, wherein Fig. 1- 1s a plan view, with parts 111 sec in accordance with'the principles of our invention,

Fig. 2 is a side elevation of one of the couplers shown in Fig. 1, the lower portion of this figure being shown in section, and

Fig. 3 is a rear end view of the coupler shown in. 2, oi Fig. 2.

The coupling illustrated in Fig. 1 of the drawing is made up of two interlocked couplers A andl-l which are preferably, though not necessarily, identical in construction. It will, therefore, be suliicient for a clear understanding of the invention to describe the coupler A in detail, the corresponding parts of coupler B being given the same reference numerals distinguished by the exponent a. The coupler A consists of a conduit or gasket g member and a coupling member 11 which is longitudinally sliduble and to a limited extent rotatable, on the conduit member. The forward end of the conduit member is formed with, a recess 12 to provide a seat for a gasket 13 and is provided at its other end with a nipple or union 1% for connection with a rubber hose or other tubular structure. The outer surface of the conduit member is provided with diametrically arranged outstanding projections 15, the rear faces of which are curved as indicated at 10.

The coupling member 11 is provided with slots 17 through which the projections of the conduit member extend, the slots being preferably somewhat wider than the projections so as to permit a rotational movement of the coupling member with relation to the conduit member. The coupling member 11 is provided on one side with an undercut lug 18 and on the opposite side with a forwardly projecting wing or arm 19 provided at its outer end with a lug 20 formed with an undercut recess 21. The lug 20 interlockswith a lug 18 on the coupler B and the lug. 18 of coupler A isengaged by the coking lug 20 on the arm 19 of coupler B. 22 is a substantially lJ-shaped yoke, the ends of which are pivoted by means of a bolt 23 to ears 24 formed on the bottom of the coupling member 11, the bolt being held in place by studs 25, 25. The legs 26 of the being taken on line 33,

the proiec ions yoke 22 are preferably curved and engage the curved surfaces 16 of the pro ect1ons 15') on thecoiiduit member. The top portlon ot the yoke is formed with a projecting pad 27 against which is adapted to bear a wedge 28nio1uite'cl EOSlKlG laterally ot the coupling The interlocking of the couplers is eiiected by releasing the pressure of the wedges 28, 28 on the yoke men'ibers, whereupon the springs 3:2, 32 more the yoke members rearwardly so as to release the pressure of the yokes-on the projections 15, 15 The coupling members 11, 11 may then be moved longitudinally of their associated conduit members to permit the lugs 20, 20 of the arms 19, 19 to be brought into preliminary engagement with the lugs 18, 18 by a lateral lll-JCGlll't-ZlliYOf the couplers A. and B. This preliminary engagement holds the conduit members 10, 10 in horizontal alignment. The wedges may then be driven in the direction of their smaller end to force the yokes 22, 2:2l( 1wa 'cl, thereby causing the conduit members'to be forced tightly against each other. The pressure exerted between the conduit members reacts upon the couplingmembers to tighten the interlocking engagement between said members.
